This invention relates to new and useful improvements in balersespecially adapted for baling hay and like material. a

, The principal object of the present invention is to provide a balerwhich will permit the baling of hay and like material in a quick,uniform and l substantially effortless manner.

Another important object of the invention is ,to provide a hay baler ofsimple design which will cost substantially less to manufacture thanconventional balers. 1

Another importantobject of the invention, is to provide a hay balerespecially adapted for use by small farmers who cannot afford morecomplic'ated and costly balers such as the market at present presents.

Application July 13,194 Serial No. 450,141 r 1 Claim. (01. mo -5)Otherobjects andadvantages of the invention will become apparent to thereader of the following description;

In the drawings:

Figure 1 is a side elevational View. Figure 2 is a top plan view. Figure3 is a section on the line ure 2. h l

Figure 4 is a cross section onthe line 4-4 of 34% of Fig- Figure 5 is afragmentary detailed sectional view through the drive means.

Referring to the drawings wherein like immerals designate like parts, itcan be seen that the present invention includesa box A made up of abottom wall 5, side walls 6 and a top wall I which extends for half thelength of the entire box. The top wall 1 defines the length of thecompression chamber 8, at one end of which is a vertical partition 9 andat its opposite end a one of the rack bars M to prevent return of thefollower l3.

A cross pin 21 is provided on the hand bar 24 and has its end portionsprojecting laterally and into slots 28 in oppositeside portions of asleeve This sleeve 29 has its lower portion bifur- 29. cated as at 30 soas to straddle the peripheral portion of the gear 2| so that the edgeportions 3! of the sleeve 29 will act as teethmeshing with the teeth ofthe gear 2|.

, Obviously by lifting the sleeve 29 and moving the bar to the left inFigure 3, and then dropping the sleeve 29, the sleeve will connect thebar 24 with the gear 2|, so that when the bar is a closed compressionchamber occupying subhinged door In through which baled hay can bemoved. Suitable clamp or detent means II is provided for the door l0.Numeral l2 denotes slots, to accommodate the tie wires for thecompressed hay.

Operative in the compression chambers is a presser or follower [3 fromwhich extends elongated racks l4, l4 slidable through openings [5 in thepartition 9. These racks l4 have depending legs 16 at the lower ends ofwhich are mounted grooved rollers l1 riding on rods or rounded tracks I8.

Extending transversely between the side walls B of the box 5 is ashaftl9 having its ends jour naled in bearings 20 and having a pair of gearmoved toward the right in Figure 3, the consequent rotation of the gear2| and the gear 22 by the shaft I9 cause movement of the rack bars 14 tothe left in, Figure 3, moving the follower [3 against hay which has beendeposited inthe compression chamber 8 through the hopper 35.

While the foregoing specification sets forth the invention in specificterms, it is to be understood that numerous changes in the shape, sizeand materials may be resorted to without departing from the spirit andscope of the invention as claimed hereinafter.

Having described the invention, what is claimed as new is:

A hay baler comprising an elongated box-like structure including abottom and side walls, and

stantially one-half the length of the structure,

the remaining half being openat the top therethe structure contiguousthe side walls, apair of rod-dike tracks fixed to the bottom of thestructure in said open-top half contiguous said side walls,longitudinally spaced legs, depending from the rack bars and havingroller-equipped lower ends riding on said tracks, apair of axially,aligned gear wheels mounted on said sidewalls and meshing withsaid rackbars, and means to rotate said gearsin unison in opposite directions,respectively, includingfla hand bar extending upwardly out of saidopen-top.
